Incredible - am wondering something similar can be done with EEG

You can probably do with with a EEG headband already. There is also already eye tracking software. No need for an implant.

In your case, would you like to wear a brainwave sensor, so to manipulate your laptop directly ?

Applying electrical current DIRECTLY to the brain: what could possibly go wrong?

Sounds like https://en.wikipedia.org/wiki/Transcranial_magnetic_stimulat..., which has a pretty extensive DIY scene.

I've long been interested in this area, but your brain is not something you experiment with willy-nilly: if you do damage, it's not like bricking your raspberry-pi while trying some cool things. That's why direct electrical or magnetic stimulation sound scary to me.However, there are other ways to experiment! I think the most amenable one is the Dream Machine (https://en.wikipedia.o

Direct electrical stimulation of the brain might just work.

Almost out of the loop about Neuralink's tech. Is it EEG?

You're mocking the parent but isn't this what most BCIs do? Electrodes + signal processing to estimate some output.
